Per Eric Leonard on KFI, the second, more militant illegal immigration march in MacArthur Park in Los Angeles has turned violent, with protesters throwing rocks at police, and the police responding with rubber bullets. A couple reporters were hit by the bullets. Breaking...

Witnesses said police wearing riot gear and wielding batons gave no warning before firing at rally participants gathered at MacArthur Park, CNN reported. Police said a protester knocked down a motorcycle officer, the news channel said.

Around 6 p.m., after police tried to disperse a group of demonstrators who had moved off the sidewalk into Alvarado Street, some of the few thousand participants still in the park started throwing plastic bottles and rocks at officers. Then, several dozen riot police, clad in helmets and carrying batons, started clearing the park, firing a few dozen volleys of foam bullets into the crowd... Several people -- including 15 police officers -- were hurt, but most, if not all, of the injuries appeared to be minor. However, late Tuesday, a staff member from Telemundo's newsroom confirmed that one reporter and three camera operators from the Spanish language TV station had been injured and were taken to a hospital by police. There was also a report that a Fox 11 reporter and camera operator had been injured... ...Another confrontation cane around 6:50 p.m., still well before nightfall, when a police car blazing its lights was bombarded by bottles and clothes as it passed.

That's one of them in the third picture from the LAT slideshow above. Tony Valdez - now apparently on the same station - is incensed.

UPDATE 3: Here's video of Telemundo crew being surprised by the riot line. It includes shots of demonstrators throwing rocks.
